Relation of parietal cell and thyroid antibodies to the state of gastric mucosa and basal serum gastrin levels during a 6-year follow up

Abstract

Two groups of volunteers (199 in total, 149 of whom were a random sample of an urban population) were examined twice, with a 6-year interval, for the occurrence of parietal cell antibody (PCA) and thyroid microsomal antibodies (TMA). The antibody findings were compared with the antral and fundal gastric mucosal state, and with the fasting serum gastrin-17 level. During the study period, two new PCA and four new TMA cases appeared. There were no significant changes in the state of gastric antral/fundal mucosa in relation to PCA and/or TMA persistence or appearance, as compared with the gastric mucosa changes in the whole random population sample. However, a good correlation was observed between PCA and basal serum gastrin elevation.
